工業(ye)的(de)發展，生產的(de)擴(kuo)大(da)，通風(feng)(feng)管(guan)道系統成了各大(da)工廠(chang)，商場，車間，醫院(yuan)，寫字(zi)樓等地方不可或缺的(de)一部(bu)分。從而(er)降低(di)空(kong)(kong)間內(nei)有害物質(zhi)(zhi)的(de)濃度，使(shi)空(kong)(kong)間內(nei)空(kong)(kong)氣得到流通。利用(yong)自然通風(feng)(feng)散發有害物質(zhi)(zhi)，先局部(bu)排風(feng)(feng)，當(dang)其不滿(man)足通風(feng)(feng)條件時，會(hui)在采(cai)用(yong)全面排風(feng)(feng)。

通風管道系統概述

　　通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)道系(xi)統(tong)是為(wei)了空(kong)氣流通(tong)(tong)(tong)，降低有(you)害物質而(er)建立(li)的一(yi)種設施。通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)的風(feng)(feng)(feng)管(guan)制(zhi)作以及(ji)安裝所(suo)用(yong)板材(cai)和其他所(suo)用(yong)材(cai)料(liao)應符合設計及(ji)國家(jia)現(xian)行標準(zhun)的規定。通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)道按材(cai)質分：一(yi)般有(you)：鋼(gang)(gang)(gang)(gang)板風(feng)(feng)(feng)管(guan)(普通(tong)(tong)(tong)鋼(gang)(gang)(gang)(gang)板)、鍍鋅板(白鐵(tie))風(feng)(feng)(feng)管(guan)、不銹(xiu)鋼(gang)(gang)(gang)(gang)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、玻(bo)璃鋼(gang)(gang)(gang)(gang)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、塑料(liao)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、復合材(cai)料(liao)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、彩鋼(gang)(gang)(gang)(gang)夾心保(bao)溫板通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、雙面(mian)鋁箔保(bao)溫通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)、單面(mian)彩鋼(gang)(gang)(gang)(gang)保(bao)溫風(feng)(feng)(feng)管(guan)、涂(tu)膠布通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)(如(ru)礦(kuang)用(yong)風(feng)(feng)(feng)筒)、礦(kuang)用(yong)塑料(liao)通(tong)(tong)(tong)風(feng)(feng)(feng)管(guan)等(deng)。

通風管道應用

　　通風(feng)(feng)(feng)(feng)管(guan)道系統(tong)一般有(you)：凈(jing)化系統(tong)送(song)回風(feng)(feng)(feng)(feng)管(guan)、中(zhong)央空調通風(feng)(feng)(feng)(feng)管(guan)、礦(kuang)用(yong)抽放(fang)瓦(wa)斯管(guan)、工業送(song)排風(feng)(feng)(feng)(feng)通風(feng)(feng)(feng)(feng)管(guan)、環保系統(tong)吸排風(feng)(feng)(feng)(feng)管(guan)、礦(kuang)用(yong)涂膠布風(feng)(feng)(feng)(feng)筒等(deng)。主要應用(yong)在工廠(chang)廠(chang)房(fang)的(de)散熱(re)，排塵(chen)，醫藥食(shi)品(pin)車(che)間(jian)的(de)凈(jing)化系統(tong)，商場，醫院(yuan)及寫字樓的(de)中(zhong)央空調的(de)送(song)風(feng)(feng)(feng)(feng)等(deng)。

通風管道的設計

　　通(tong)風(feng)管(guan)道(dao)(dao)的(de)(de)設(she)(she)(she)(she)計(ji)原則(ze)應(ying)(ying)遵(zun)循“大管(guan)讓小管(guan)，有壓(ya)讓無壓(ya)”的(de)(de)原則(ze)，解(jie)決(jue)各(ge)種(zhong)通(tong)風(feng)管(guan)道(dao)(dao)相碰的(de)(de)問題(ti)。對于比較(jiao)復雜的(de)(de)民(min)用建(jian)筑(zhu)，在設(she)(she)(she)(she)計(ji)階段，各(ge)工(gong)(gong)種(zhong)(暖通(tong)、給(gei)水排水，供電照(zhao)明與(yu)建(jian)筑(zhu)專業)首先應(ying)(ying)協(xie)商好空(kong)(kong)間分隔，定出每種(zhong)管(guan)道(dao)(dao)的(de)(de)標高范(fan)圍。一般情況下(xia)不得越出給(gei)自己規(gui)定的(de)(de)界(jie)限。施工(gong)(gong)前，工(gong)(gong)程師應(ying)(ying)把(ba)管(guan)道(dao)(dao)布局畫在圖紙上，發現(xian)問題(ti)及時尋(xun)找(zhao)解(jie)決(jue)方案。為了減(jian)少(shao)投資，節(jie)省空(kong)(kong)間，有些敷設(she)(she)(she)(she)無坡度要求(qiu)的(de)(de)管(guan)道(dao)(dao)，可以穿梁敷設(she)(she)(she)(she)。
